摘要：

Recently, spin-one wave functions in four dimensions that are conformal primaries of the Lorentz group SL(2, C) were constructed. We compute low-point, tree-level gluon scattering amplitudes in the space of these conformal primary wave functions. The answers have the same conformal covariance as correlators of spin-one primaries in a 2d CFT. The Britto-Cachazo-Feng-Witten (BCFW) recursion relation between three-and four-point gluon amplitudes is recast into this conformal basis.
